阿里雲 centos 環境配置與 django 部署

1. 免密碼登陸

# 本機生成密鑰, 並將 pub 復制到阿里雲服務器上
$ ssh-keygen -t rsa -P ''  # -P表示密碼，-P '' 就表示空密碼 $ scp ~/.ssh/FILENAME.pub root@server_ip:/root # 阿里雲服務器上將 pub 放入 authorized_keys 中 # cat FILENAME.pub >> ~/.ssh/authorized_keys # chmod 600 ~/.ssh/authorized_keys

2. yum

默認的環境並不 OK.

1) 運行出錯提示    No module named yum

解決方案: #vi /usr/bin/yum 將 #!/usr/bin/python 修改為  #!/usr/bin/python2.4

2) 下載yum的配置源

mkdir /etc/yum.repos.d/
cd /etc/yum.repos.d/
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

3) 運行yum makecache生成緩存

若重新安裝 yum

查看yum包   rpm -qa|grep yum 

卸載   rpm -qa|grep yum|xargs rpm -e --nodeps 

安裝:

1) 下載安裝所需的三個文件, 下載地址: http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/

yum-3.2.22-40.el5.centos.noarch.rpm
yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
yum-metadata-parser-1.1.2-4.el5.x86_64.rpm

2)  安裝命令

rpm -ivh yum-*

注意：yum和yum-fastestmirror相互依賴，所以需要同時安裝。

3) 恢復 /etc/yum.conf 文件, 一般卸載時會自動備份.

3. 開發環境依賴包更新

$ yum update
$ yum -y install gcc g++ autoconf
$ yum -y install openssl openssl-devel zlib zlib-devel

4. python

手動編譯安裝 Python, 官網下載源碼即可.

./configure  --enable-shared  # if not, error -- libpython2.7.a:  could not read symbols: Bad value
make
make install

此時運行 python 可能報錯: 

python: error while loading shared  libraries: libpython2.7.so.1.0:

  cannot open shared object file: No such file or

 解決方案:

$ vim /etc/ld.so.conf.d/python2.7.conf
# 加入內容：
/usr/local/lib

#保存退出后運行：
$ ldconfig

pip 與 庫. 源碼 setup.py 安裝 setuptools 與 pip

yum install -y  python-setuptools python-devel
sudo easy_install -U distribute

5. 手動安裝 git

http://distfiles.macports.org/git/ 下載最新 git

$ yum install gettext-devel

$ wget http://distfiles.macports.org/git/git-2.1.1.tar.gz
$ tar zxvf git-2.1.1.tar.gz
$ cd git-2.1.1
$ autoconf 
$ ./configure
$ make 
$ make install

6. MySQL

# rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm  # 導入第三方源webtatic
# yum remove mysql mysql-*
# yum install libmysqlclient15 --enablerepo=webtatic
# yum install mysql55 mysql55-server --enablerepo=webtatic
# service mysqld start

安全性配置

# mysql_secure_installation  # secure settings

 字符編碼設置:

http://www.cnblogs.com/misspy/p/4033352.html

開機自動啟動

# chkconfig --levels 235 mysqld on
# service mysqld restart

 

7. apache2 與 mod_wsgi

# yum install httpd httpd-devel

# chkconfig --levels 235 httpd on
# service httpd restart

 

源碼安裝 mod_wsgi https://github.com/GrahamDumpleton/mod_wsgi
